The present invention provides an electric switch comprising an actuator, a first electrical contact which acts are a fulcrum, a second electrical contact and a contact bridging member. The contact bridging member is slidably movable over the fulcrum and pivots thereabout whereby to bring the leading or trailing end of the member into or out of contact with the second contact. Platform means are provided on the side of the fulcrum remote from the second contact to support the member in a position out of contact with the second contact. A further embodiment provides an electrical switch comprising a plurality of such switching assemblies. A single actuator is adapted to move both the contact bridging members, and the fulcrums of the first and second switch assemblies are positioned to obtain multiposition characteristics.
